i actually tried that a few times and it didnt work srrrry

anonymous · Answer

suppose you have two numbers like 12 and 80

12=2*6
12=2*2*3

80=2*40
80=2*2*20
80=2*2*2*10
80=2*2*2*2*5

80 has the highest number of 2's, 4 f them, it also has a five
12 has a three not covered by the 80
so a multiple of both 12 and 80 has to be divisible by 2 four times by five and by three .

we can multiply those together to get the lowest multiple 2*2*2*2*3*5=240
so 240 is the lowest common multiple
